Replaced inductors with board traces and replaced Arco mica compression trimmers with fixed capacitors. 100 W across the band with no tuning required, using MRF173CQ, 0.059" GETEK, 0.050" traces, and ATC 100B porcelain caps. This board had a problem with overheating the trace coming out of the drain - it would get so hot it would delaminate and eventually vaporize if not kept cool. See revised version at the bottom of the page.
 

Original design notes. These are pretty useless and are here for historical and entertainment purposes only.
 

Final version, with fatter trace, and target power reduced to 80 W.
